Mini-Max Configuration
Notes
The Mini-Max must be properly
programmed to have the corrected and
uncorrected outputs available on TB1.
Per the Mini-Max Operator’s Guide:
• Item No. 093 should be set to
Code 0. This will select the
Corrected output to be on for TB1
slot 2.
• Item No. 094 needs to be
programmed to Code 2 in order to
select the Uncorrected output to be
on TB1 slot 3.
• Item 096 and 097 should be set to
Code 2, which will set the display
to 6 digits and match the reading
length stored in the MTU.
• Item No. 115 should be left at the
default of 0 which will give a pulse
width of 0.0625 Sec.
• Item No. 090 and 092 need to be
programmed to match the scaling
in the MTU. Ex. Code 1 = CU FT x
10; Code 2 = CU FT x 100.
Other settings may be needed for the
Mini-max to operate correctly. See the
Mini-Max Operators Guide for further
instructions.
